Logitech Unifying Receiver (Dongle)

The [Logitech Unifying Receiver][1] allows you to connect multiple (up to 6) devices through one single, small dongle. The dongle itself is made up mostly of the USB connector, meaning it's small and so stays out of the way, and is unlikely to be bent or broken if knocked.

Pro

Works whilst charging

Though the mouse works wirelessly, it's recharged via USB. When recharging, the mouse continues to work .NB: The mouse still communicates wirelessly, so requires one USB for the Logitech Dongle, and one for the charge cable.

Useful accessories

A travel case, a USB charge cord and a USB-to-outlet-power adapter, and a USB extension cord for the receiver.

Pro

Included software further eases work

The included Mouse Manager software allows you to assign different functions to the buttons such as hotkeys, Windows commands, or media control.

Static strain can also be reduced by pressing and holding a button momentarily to simulate continuous pressing.
